LIQUID-APPLYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 764,796, dated July 12,1904.

Application filed July 3, 1903. Serial No. 164,284. (No model.)

To all whom it may concern:

Be it known that I, LEVI WALTER DAvIs, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inLiquid-Applying Apparatus, of which the following is a specification.

My invention relates particularly to improvements in that class ofdevices known as gummers, paste-appliers, mucilage-distributers, and thelike; and its object is to provide a convenient and economical device ofthe class described suitable in its scope, which ranges from a smalllabel to a length of wallpaper.

Another object in view is to evenly coat the entire surface of theapplied material without waste of the liquid, also for the rapidmanipulation of material, the cleanly manner of the said application, aswell as the convenience thereof, and to provide a reservoir which issusceptible of ready transportation. The reservoir is adapted to bereadily cleansed, while at the same time it is so arranged as topractically prevent evaporation of its contents.

I attain these objects by simple devices hereinafter fully described,and shown in the accompanying drawings, in which Figure 1 is aperspective View of the apparatus; Fig. 2, a section on line a b of Fig.1, showing the interior arrangement; Fig. 3, the plan of a fragment ofthe hinged cover, and Fig. 4 the end elevation of the same.

In the drawings, 1 1 represent the rectangular ends of a thin metalliccase, the lower edges of which rest upon the table, bench, or floor uponwhich the apparatus is placed. The upper edges 2 2 extend above thelevel of the top surface, forming guiding-flanges for the strips ofmaterial passed over the roller in the process of receiving a coat ofthe liquid. The bottom of the case 3 is preferably made cylindricallyconcave, so that the liquid contained therein shall be deepest in thecenter, and that form obviously permits use to be made of the liquid solong as any shall remain within the case. The sides I iand half-top 5,together with the bottom 3, are preferably made of one piece withoutjoint, formed into the proper shape and united to the ends 1 1 bysolder. The other top, 6, is made separate and united to the side 4 by ahinge-joint extending its entire length. The inner edges of both toppieces are bent downwardly in conformity with the radius of the roll 8and are arranged to barely clear its periphery when the said roll isresting in its bearings 7 7 which are V- shaped, open at the top, and ofsuflicient angle to allow the roll to be withdrawn. The bearings 7 7have outwardly-extending arms secured to the ends 1 1 and also half-top5. The hinged top 6 normally rests on the opposite arm, but is readilyremovable therefrom. The roll is a hollow cylinder having projectingpintles 9 9 at both ends adapted to rest and revolve in the openbearings 7 7 It is desirable that the roll 8 be made light enough tofloat in the liquid contained in the reservoir, as by so doing it willrise in its open bearings, fill the opening at the top between thecovers, and hence prevent evaporation of the liquid in the reservoir.The thin film of liquid which may be upon the surface of the roll afteruse materially aids in forming an air-tight joint in the manner ofapacking.

In operation the cover is turned back, the reservoir formed in the casefilled with the liquid to be applied, the cover replaced, and as theperiphery of the roll is always slightly above the otherwise smoothsurface of the top the friction of the article moved over the top causesit to revolve and deposit an even film of the fluid, in which the rollis semisurrounded on the lower surface of the article. So long as anyliquid remains in the reservoir this action will be continued. It is notnecessary to remove the remainder of the liquid after use, as the case,in combination with the roll, forms a sealed receptacle for itsmaintenance; but if for any reason it becomes desirable to change thecontents or cleanse the reservoir it is readily accomplished by turningup the top and withdrawing the roll.

While this apparatus is specially designed for gumming labels, applyingliquid paste to wall-paper, blanks, and like uses, it is evident that itmay be used with equal readiness in applying any liquid or semiliquidprepation.

Now, having described my invention, what I claim, and desire to secureby Letters Patent, 1s

1. In a liquid-applying apparatus, a buoyant roll, situated partiallywithin a reservoir and adapted to be revolved by the superficial contactof material passed over its exposed periphery, of continuous flanges,depending from each side of the opening in the cover of the saidreservoir, forming in connection with the longitudinal side Walls of thesaid roll, a normally non-evaporative chamber below, all substantiallyas shown and described.

2. In a liquid-applying apparatus, the combination of a case containinga reservoir provided with a hinged cover or covers having a longitudinalcentral opening, of a distributing-roll loosely journaled within saidcase; of downwardly-extending flanges, integral with the covers,contiguous to and on each side of the said roll and ofupwardly-projecting end walls forming guides, all substantially as andfor the purposes set forth.

3. In a liquid-applying apparatus, the combination of aself-sealingreservoir, of a hinged cover or covers, of a distributing-roll, and ofguide-walls above the roll-surface.

4:. A liquid-applying apparatus comprising a case, a cover in two parts,either or both hinged to the side walls, journal-hangers attachedpermanently at each end and inside the case, afloating cylindrical roll,provided with pintles at each end and adapted to rest and revolve insaid hangers when depressed, and having a portion of its peripheryslightly above the surface of the covers, and guidewalls at each end ofthe apparatus, all substantially as and for the purposes as set forth.

In testimony whereof I affix my signature in presence of two witnesses.I
